Absolutely one of the most useful apps I have downloaded in a long time. Random generators, some specific to a particular game but most interchangeable and usable across just about any game. Characters, names, NPCs, towns, weather, dungeons, monsters, spells, magic, etc...any of those and more can be generated in seconds. Even a die roller is included with common dice rolls to individual poly dice.
I'm glad to finally see this app make it over to the Amazon store so I can use it on my Fire. Adventuresmith makes running tabletop rpgs on the fly a lot of fun, and helps minimize the amount of prep I need to do on those nights when I just want to wing it.
